Hi
I have an option to buy for like 20$ a prebuilt HP 280 G1 PC and convert it into a backup/storage PC for me and my family. The OS will be OpenMediaVault booted from USB*. I have 1Gbs ports on my router and did some tests with this setup (using one 320GB and one 4TB drives I could find) showed me 100-130MB/s RW speed, which is ok for me. Power consumption is like 29-33W with 2 drives, not a problem for me. Running noise is acceptable.
(I could probably switch the 280 G1 for a HP 3500 for similar price, but the 280G1 case has 2 3.5" bays in it so I wouldn't have to make workarounds to stick 2 drives in the 3500 case )
I'm assuming at the start (at least half a year/one year, maybe even more until we will get used to it being the main storage place, if ever ) that the Storage-PC will be booted maybe 1-2 times per week (or maybe even less often) to just backup stuff on it, copy something that is needed and then power off until next time. It won't work 24/7 or even during "day hours" (8-24, power off for night). For actual storage of data that we need for daily usage we have SSDs/HDDs in our PCs/laptops. Crucial data for us will also be stored on external HDDs (each one of my family members has a dedicated external drive for that ), so most important stuff will have at least 2 copies (one on Storage-PC and one on external drive). We don't want to buy 3-4 more externals for storage and then shuffle them, that's why we want to use one place for it (and since the PC costs like 20$ then it is super cheap vs getting actual NAS).
Now for the question:
I plan to stick 2 HDDs there (most likely 2x 8TBs as it has the best price-available storage-current storage needs-future storage needs ratio compared to 6TBs or 10TBs drives).
Should I get CMR or SMR drives?
Since the storage PC won't work as a streaming platform, data won't be read/write to it on constant matter, I won't enable disk spindown or config power management on it etc so I think that the cheaper SMR might be an good option for this, as it costs less where I live. Disk at the moment which I compared:
2x SMR Seagate BarraCuda 8 TB (ST8000DM004)
2x CMR WD Purple 8 TB (WD84PURZ)
2x CMR WD Blue 8 TB (WD80EAZZ)
2x CMR WD Black 8 TB (WD8001FZBX)
And the BarraCuda cost 22% less than WD Purple, 37% less than WD Blue and 84% less than WD Black...
Thank you, have a nice day
* I plan to have at least 2 USB sticks with OMV configuration 1:1 on them so if one fails I can plug the 2nd USB. Though if in the long run the USBs sticks due to power on/power off cycles would fail rather fast I will get a small SSD and boot from it (and use the 3rd SATA port on it if it won't be already used for a 3rd HDDs).
